BRS Pros helped Richard with his crawl space and here are some steps we took… Mold Remediation – Phase I of this work consists of cleaning the crawl space sub-floor of wood decaying fungi and organic growth. After cleaning, Phase 2 consists of fogging the crawl space. Phase II will kill 99.9% of mold spores and will inhibit the growth of mold and mildew. Decay and organic growth was treated and cleaned, however, it is likely that some staining will remain due to any pre-existing damage to the wood members. Hydra-Channel – A clean trench was dug adjacent to the foundation footing along the all interior perimeter foundation walls, the hydra-channel was installed according to manufacture’s instructions adjacent to the footing. The Hydra-Channel engineered fusion welded high strength polyethylene water system will remove storm water up to 70% faster than a pipe and stone system, it will allow water to flow freely to the in-ground sealed sump pumps/basins located in the right interior and front left of the crawlspace. Sump Pump – Installed our GrateSump basin with a removable (flush with floor) lid covered with stone in left front corner of crawlspace. The system includes 1/3 HP cast iron primary pump with dual float cage that protects debris from float. Included is a deluxe controller that monitors pump and power conditions and will sound an alarm if problems are detected or a high water warning in the sump, additionally, it activates the pump weekly to exercise and extend the pumps life. Vents – Foundation vents were completely sealed with poly-foam insulation from the interior of the crawl space preventing exterior air and moisture from getting into the crawl space. Insulations & Wall Liner – Installed fiberglass blanket insulation with white vapor barrier to interior perimeter foundation walls. Insulation is 4″ thick which offers an R-13 insulation factor (code compliant for new construction). Insulation shall be hung approximately 6″ from the top of the interior masonry foundation wall to provide a termite inspection and will cover the wall to approximately 4″ off the ground. A reinforced 9-mil wall vapor barrier was mechanically fastened to foundation wall prior to fiberglass insulation to prevent any moisture/condensation from wall to contact insulation. Thermax – Installed our 2″ thick (R-13) Thermax rigid closed cell insulation over foundation wall liner. Class A fire-rated. The THERMAX rigid insulation was mechanically fastened to the foundation wall and the crawl space door to insulate the perimeter exterior walls. All Thermax joint seams were taped. THERMAX is a glass-fiber-infused polyisocyanurate foam core laminated between 1.0 mil smooth reflective aluminum facers on both sides. Ground Liner & Radon Ready – Installed our Premium (walk on, store on) 15-mil white 100% woven reinforced radon ready crawl space system. The liner was mechanically fastened with nails designed for foundation walls to provide a permanent fastening system. (Caulking or taping liner to foundation walls is a temporary system and will become a maintenance issue.) The premium ground liner was nailed/sealed approximately 6″ to 12″ above the earth in the crawl space to the foundation wall. A radon piping system was installed below the ground liner, the piping system will be used in the future when the home is tested for radon gas and requires a complete radon system. 15-mil woven ground liner will control moisture vapor and dampness from the ground. Most crawl space liners are partially reinforced, our woven liner is 100% reinforced and tough unlike competitive brand liners that are only 10% reinforced. This product will not off gas (known on Google as “crawl space cat urine odor”, go ahead and check it out), we guarantee it!! Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to the liner.
